A source close to the show says the duo’s constant sniping may carry both contestants through to the season finale. “Kenya and Brandi likely will make it close to the end,” the insider says. “They make for good TV!”

What’s not to love? Kenya, the former Miss USA 1993, and Brandi, an ex-model, have been at odds from the start. “Kenya has it out for Brandi,” notes the source. During a challenge to make and sell pies at a bakery, “Kenya hit Brandi in the face with a pie. Brandi got Kenya back, but it was Kenya who started the fight.”

Kenya also sabotaged Brandi’s budding friendship with actress/contestant Vivica A. Fox. “Brandi and Vivica were hanging out every night, but suddenly Vivica stopped talking to Brandi,” says a second source. “Kenya somehow got involved. I don’t know what she said, but Vivica won’t speak to Brandi.”

Adding to the tension was the fact that throughout much of the show’s production, the first source says, the two were on the same team: “Brandi had to be nice to Kenya, because she needed Kenya to work. But Kenya is lazy and is incredibly hard to deal with. She makes everyone miserable.”

The RHOA egomaniac who antagonizes her castmates — including the infamous scepter from the recent reunion show — is just as compulsively watchable on Apprentice, treating the staff like hired help. “She has these crazy demands and bosses everyone around,” says the first source. “During a car ride to another location, she ordered the driver to have a lemonade to be ready for her when she arrived. Another time she demanded that one of the stylists carry her purse around for her.”

According to the second source, Brandi, 41, is well-liked by the rest of the Apprentice cast, which includes Kate Gosselin, Geraldo Rivera, Kevin Jonas and others.
